cheap 42CrV6 alloy structural steel

42CrV6 is a kind of alloy structural steel .Quenched and tempered steel, having high strength and high yield, mechanical properties better than 40Cr. Cold deformation plasticity and machinability belong to medium, thermal sensitivity is small, but there is a tendency to temper brittleness and white point sensitivity. Usually in the quenched state use .
